Cohoes Falls [Kahon:ios, Mohawk for "Canoe Falls"] is a waterfall on the Mohawk River shared by the city of Cohoes and the town of Waterford, New York, United States. Discovered by the indigenous Mohawk tribe, the falls were originally called Ga-ha-oose or Ga-ho'n'-yoos, which is believed to mean "The Place of the Falling Canoe." Cohoes historian Arthur Masten wrote in his 1880 history that the phrase might mean "Potholes in the River," referring to the potholes that appear in the riverbed when it is dry. In the oral tradition of the Haudenosaunee (Iroquois), the Cohoes Falls are the site where The Great Peacemaker, performed a feat of supernatural strength, convincing the Mohawk people to become the founders of the Iroquois League of Nations or Confederacy.
